Editor’s Comments Ladies and gentlemen welcome to this edition of this wonderful magazine. Our aim is to keep you informed on risks which we encounter everyday as we do business. In this issue I will talk about cybercrime which is a concern to governments and the cooperate world. The Oxford dictionary denes cybercrime as criminal activities carried out by means of a computer on the internet. Others dene it as crime which a computer is the object of the crime or is used as tool to commit the offence. This could be child phonography, hate crime or hacking of organizational computers. With the amount of data stored in data bases around the world, this has made the use of the internet very important. Data can be easily accessed at the press of a button. The infusion of the internet has changed the way we handle data and at the same time more threats to held information has arose with this infusion. Fraudsters have managed to transfer money from different bank accounts and have remained unapprehended. Cooperate data has disappeared when computer induced viruses and malware attacked company data bases. In the USA a teenager boy managed to hack into the Pentagon computer system for fun. This exposed the data security of the Pentagon. Software designed to disturb or cause damage to computers have been designed and are being sent out to different computers through emails which once opened pass the virus to the computer leading to its malfunction. In the last year cybercrime has been rmly established as one of the biggest threats to democracy, privacy and health and safety. Terrorists groups are also now using the internet to champion their cause. While money laundering is at a huge scale on the internet. Child phonography is also a huge concern as children are targeted by unruly elements and subjected to horric pictures aimed at inuencing their behavior. Recently cyber criminals have been demonstrating that their activities are becoming more about nancial gain and recognition. Although this was always the motivation, after all the easiest means of making money is to get hold of personal records and sell them on the dark web. We are witnessing a notable increase of attacks for this purpose. To prevent cybercrime from taking place in organisations there is need to employ cyber security. Cyber security is the body of technologies, processes and and practices designed to protect networks, computer programs and data from attack, damage and unauthorized access. This include Application security, Information security, Network security, Operational security. Business continuity plans and End user education. One of the most problematic elements of cyber security is the quality and constantly evolving nature of security risks. In other words the threat is advancing quicker than we can keep up with it. As a result cyber criminals always change their ways and continue to commit crimes and untold damages to unsuspecting people, In conclusion the risk of cybercrime is real and as risk personnel should be able to come up with security measures to minimise this risk. Best Regards

Editor G. Sibanda

Weighing up risk

In excess of 60% of the SADC group of countries combined GDP comprises goods that are weighed at some point in their transition to market, whether locally or as exports. Weighing is therefore profoundly important. Risks are Higher in Industrial Sectors Weighing breaks down into basically retail weighing, comprising goods sold through large and small retail outlets, and the much larger component termed industrial weighing. The risks associated with decient weighing within the retail sector are comparatively low, but the same cannot be said for industrial weighing and these risks have been growing. Prior to the advent of the digital age, globalization, expanding trade within the SADC region, the introduction of axle weighing overloading regulations throughout SADC, the introduction of SOLAS regulations which has impacted all global containers exports by sea, industrial weighing was a mundane process involving trucks driving over weighbridges with the results being written down, and eventually captured into an accounting system.


In this “mundane age” of industrial weighing risks of decient weighing were low, and the scale companies providing industrial weighing equipment and services were equally mundane. The business of these participants was essential the installation of scales and the maintenance and repair thereof. Changing Dynamics are Increasing the Risks The term “decient weighing”, includes weighing done on devices that are unapproved, weighing done on devices that are inaccurate, weighing software that is not compliant and weighing software that does not enable real time weighing data to be supplied. Understanding the signicant risks associated with “decient weighing” in today's rapidly changing market place requires one to dissect the associated risks that arise from directly from the new trade dynamics, laws and regulations and technologies that impact on and shape our industrial trade ows in today's global economy. Each of these dynamics and the associated risks can be

summarized as follows: 1. Introduction of axle weighing overloading regulation: In South Africa, the Road Trafc Act 22nd Amendment requires that, for every load, the transporter and or consignor must produce and retain proof that each vehicle in question is loaded to within permissible limits. Government weighing stations both in South Africa and the rest of SADC then weigh vehicles to ensure they are within limits. Failure to be able to prove full compliance with the Road Trafc Act 22nd amendment will result in large potential nes for non- compliance, potential nes for overloading at government weighing stations, the possible required discharging of cargoes at government weighing stations so as remedy overloading causing resultant delays and added costs and nally the possibility of insurance cover being rendered null and void in the event of an accidents. 2. Compliance with SOLAS regulations on containers shipped by sea:

Mar - Apr 2018

Weighing up risk Validity of Transporter's Third Party insurance cover called into question without proof of compliant axle loading and total loading.

IMO SOLAS regulations require that, for every container to be transported by sea, the owner of that cargo must determine the gross mass of the container on an approved weighing device, and must generate documentary proof thereof in a specied format. Failure to comply with these regulations will prevent containers being allowed into departure ports risking delays and added costs. 3. Controlling in transit stock losses The volume and value of goods transported around SADC countries by road are vast. Stock losses in transit can only be controlled and managed if volumes of goods load and the point of loading and the volume of goods discharged at the point of loading are determined with great accuracy.

Weighing is the obvious way of establishing these values, and is highly effective when these values are integrated into an overall ERP system so as to make real time reconciliations possible. Solutions to Mitigate Weighing Related Risks Weighing related risks can only be mitigated through management having access to accurate and compete weighing data on a real-time basis. The provision of these types of solutions are therefore key. While a number of software companies have sought to provide these solutions, they have generally lacked the base weighing knowledge and understanding of weighing devices, which has curtailed their success. With one notable exception, most of the scale companies that historically focused on the supply, servicing and

Mar - Apr 2018

repair of scales, in the “mundane age” of weighing have continued to focus on service and repair of scales. The notable exception is Sasco, which traded as during the mundane age” of weighing as the South African Scale Company. Sasco commenced trading in 1910 and was the market leader during both the mechanical age of weighing and in the in subsequent electronic analogue age of weighing. Sasco transformation into the leading weighing data systems provider has been achieved by securing rights to the most advanced digital weighing technologies, integrating these devices with micro-computer systems capable of providing fully automated weighing solutions and the complete integration of this data to real- time ERP and cloud based solutions.

Building design must incorporate effective disaster management

All building designs must incorporate effective disastermanagement systems to allow for safe escape and the control of re and smoke. A minor design aw could potentially place people, equipment, and property at risk of death and destruction, ASP Fire CEO Michael van Niekerk warns. All buildings in South Africa need to comply with the requirements of the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977), Fire Protection, as set out in SANS 10400 Part T: 2011. Effective re-safety solutions take into account the dimensions and construction of the building, the materials used, and the occupancy and storage of items. These all fall within the prescriptive requirements set out in SANS 10400-T. Any digression from the prescriptive requirements requires a rational design to be completed in accordance with the re engineering methodology framework requirements of BS 7974. The Application of Fire Safety Engineering Principles to the Design of Buildings, supported by the published documents, form an integral part of the BS 7974 framework. A rational design is the performance-based design of re safety and prevention mechanisms and strategies in a building in order to provide the same or better re safety levels of the National Building Regulations, where the prescriptive requirements cannot be applied. This process is not elective, inasmuch as that only certain parts of the framework may be used, or that the results of the process are subjective or optional.


A rational design commences with a re-risk consultant such as ASP Fire visiting the premises, or reviewing a set of new building plans, to undertake a comprehensive evaluation of all areas of the property to inspect all areas of re safety and risk in detail. Correct and proper re-engineering principles are applied to ensure that the design complies with the life, building, re behavioural, and environmental re- safety objectives required by law. According to Van Niekerk, the three main causes of re are electrical, arson and heating equipment. “In the event of a major re that results in immense damage and the possible death of occupants, the re engineer will be held liable. Rational design takes into account the behaviour of a building during a re, meaning the structure must be designed accordingly, thereby minimising any potentially devastating impact.” Fires can be dealt with through three main actions. The rst is controlling the growth of the re to prevent it from spreading. The next is suppression, which involves cooling the re rapidly. Finally, extinguishing the re means that there is no heated substance remaining. Evacuation should also be safe and easy, while allowing unrestricted access for emergency services. The installed re-detection system must be able to detect the re as soon as possible, warn occupants, and allow them to escape in time. The qualitative review under rational design includes an architectural review, re- safety objectives, re hazards and risks, trial re- safety designs, and worst-case re scenarios for analysis. For example, consultants often ignore the building roof's geometry, and the required

substitute rectangular volume used in smoke - ll formulae. The next step is quantitative analysis according to BS7974. Here the main focus is on the development of re within the enclosure of origin, the spread of smoke, structural response and re spread beyond the enclosure of origin, detection of re and activation of re-protection systems, re- services intervention, and evacuation of occupants. Assessment against criteria is the nal step, where the re - safety designs developed during the engineering analysis are assessed to ensure that the objectives established at the beginning of the process are, in fact, met. Upon the completion of the re-risk assessment and drafting the rational design report, ASP Fire provides the client with practical actions to implement. The report comprises a detailed and documented objective re-risk assessment, as well as re-engineering calculations and analysis where required, covering all aspects of re risk and safety. “This guides the client in protecting its business, employees, and customers by providing prioritised recommendations for action, in order to rectify problem areas and strengthen existing re-safety procedures. This also ensures that the client complies with re-safety regulations for the protection of life, property, and the environment,” Van Niekerk elaborates. As part of its value-added service, ASP Fire also works closely with insurance brokers and underwriters to address a client's re risk based on the outcomes of the

This assists in preventing damage to property and products, loss of life, nancial loss, consequential loss of prot, loss of productivity, and insurance repercussions. “We also provide ammable liquid store designs and certication, special-risk re protection systems, visual safety awareness programs, SHEQ safety le drafting and implementation, emergency response and business continuity plans, emergency evacuation plan design,

ASP Fire also offers standardised and customised client training. “The client has the option to select a standard re risk and safety course, or have a customised training programme developed around individually specic needs, or the areas indicated in the re safety risk assessment report,” he states.

Return on investment through surveillance camera adoption is guaranteed. Harrison cites the case of a mine that is currently installing new cameras. “The actuaries have performed calculations on the four new cameras in terms of their cost effectiveness and in only three weeks the cameras paid for themselves twice over. This was primarily due to the fact that each week their footage led to the arrest of between 80 and 100 Illegal miners. Incurred losses from illegal mining have been totally obliterated. The successes we have experienced here have led to us embarking on a drive to enter the anti-poaching arena with our technology solutions.”

A-Gas South Africa launches US refrigerant-recovery service The company is achieving this through its association with Rapid Recovery of the US, which it acquired in 2016. A-Gas South Africa introduced its Rapid Recovery service offering for the local market at a media event held on the 1st and 2nd November 2017 at supplier Metraclark in Cape town and Johannesburg respectively. The event was attended by Rapid Recovery MD Adam Dykstra. The company is not only the largest refrigerant recovery company in the US, but in the world. “We recover more refrigerant than any other single company globally,” he reveals. “Anywhere there is a regulatory compliance for a contractor, or a demand for such compliance from a customer, there is a need for high-speed refrigerant recovery solutions,' Dykstra explains. He adds that the recovery equipment available to contractors today is offthe-shelf and bulky. “We offer a service that essentially encompasses both a technical, compliance and legal solution. We not only assist contractors in complying with the law, but also give their own customers peace-of-mind that they are dealing with professionals well-versed in the latest technology and trends.” One of these latest trends is the A-Gas Rapid Recovery

mm. “The valve uses system pressure to operate the valve mechanism. When the solenoid is powered, the system pressure will force the valve open until the system pressure drops below 0.2 MPa, when it closes automatically,” Hughes explains. The valve must be pressurised on the inlet in order to be able to function properly. The valve's state can be monitored electrically when it is open and pressurised. Monitoring with additional equipment is also possible via the 3.5 mm activation ports. The pneumatic activation chamber is designed with a small leakage to protect the valve from unwanted activation caused by small leakages into the activation chamber. Once the valve is open, it remains so until the system pressure has dropped below 2 bar. It closes
